Types

type Feature

type Feature struct {
	// The name of the feature.
	Name string `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
	// The point where the feature is detected.
	Location *Point `protobuf:"bytes,2,opt,name=location" json:"location,omitempty"`
}

A feature names something at a given point.

If a feature could not be named, the name is empty.

type Point

type Point struct {
	Latitude  int32 `protobuf:"varint,1,opt,name=latitude" json:"latitude,omitempty"`
	Longitude int32 `protobuf:"varint,2,opt,name=longitude" json:"longitude,omitempty"`
}

Points are represented as latitude-longitude pairs in the E7 representation (degrees multiplied by 10**7 and rounded to the nearest integer). Latitudes should be in the range +/- 90 degrees and longitude should be in the range +/- 180 degrees (inclusive).

	// The other corner of the rectangle.
	Hi *Point `protobuf:"bytes,2,opt,name=hi" json:"hi,omitempty"`
}

A latitude-longitude rectangle, represented as two diagonally opposite points "lo" and "hi".

func (*Rectangle) Descriptor

type RouteGuideClient

type RouteGuideClient interface {

	//
	// A feature with an empty name is returned if there's no feature at the given
	// position.
	GetFeature(ctx context.Context, in *Point, opts ...grpc.CallOption) (*Feature, error)
	// A server-to-client streaming RPC.
	//
	// Obtains the Features available within the given Rectangle.  Results are
	// streamed rather than returned at once (e.g. in a response message with a
	// repeated field), as the rectangle may cover a large area and contain a

	ListFeatures(ctx context.Context, in *Rectangle, opts ...grpc.CallOption) (RouteGuide_ListFeaturesClient, error)
	// A client-to-server streaming RPC.
	//
	// Accepts a stream of Points on a route being traversed, returning a
	// RouteSummary when traversal is completed.
	RecordRoute(ctx context.Context, opts ...grpc.CallOption) (RouteGuide_RecordRouteClient, error)
	// A Bidirectional streaming RPC.
	//
	// Accepts a stream of RouteNotes sent while a route is being traversed,
	// while receiving other RouteNotes (e.g. from other users).
	RouteChat(ctx context.Context, opts ...grpc.CallOption) (RouteGuide_RouteChatClient, error)
}

	ListFeatures(*Rectangle, RouteGuide_ListFeaturesServer) error
	// A client-to-server streaming RPC.
	//
	// Accepts a stream of Points on a route being traversed, returning a
	// RouteSummary when traversal is completed.
